Within the wide and fascinating field of radar techniques and systems, this book describes in detail a number of areas of research related to system architecture and design, phenomenology, array antennas and signal processing. The topics covered include: radar detection; phenomenology of clutter and related constant false alarm rate (CFAR) processors; Doppler techniques for surveillance radar, multifunction radar and synthetic aperture radar; clutter suppression: moving target indicators and detectors, adaptive and optimum MTI (moving target indication); rejection of jamming in space and frequency domains; concepts of radar target identification; architectural options and trend in radar signal processing; phased arrays (array theory, analysis and synthesis techniques; array elements and mutual coupling effects; architecture, elements, design criteria and low-sidelobe techniques for active arrays); bistatic radar; and space-based radar. The book is primarily aimed at radar engineers and researchers, as well as at students of advanced radar.

Advances in Bistatic Radar updates and extends bistatic and multistatic radar developments since the publication of Willis' Bistatic Radar in 1991. New and recently declassified military applications are documented, civil applications are detailed including commercial and scientific systems and leading radar engineers provide expertise to each of these applications. Advances in Bistatic Radar consists of two major sections: Bistatic/Multistatic Radar Systems and Bistatic Clutter and Signal Processing. Starting with a history update, the first section documents the early and now declassified military AN/FPS-23 Fluttar DEW-Line Gap-filler, and high frequency (HF) bistatic radars developed for missile attack warning. It then documents the recently developed passive bistatic and multistatic radars exploiting commercial broadcast transmitters for military and civilian air surveillance. Next, the section documents scientific bistatic radar systems for planetary exploration, which have exploited data link transmitters over the last forty years; ionospheric measurements, again exploiting commercial broadcast transmitters; and 3-D wind field measurements using a bistatic receiver hitchhiking off doppler weather radars. This last application has been commercialized. The second section starts by documenting the full, unclassified bistatic clutter scattering coefficient data base, along with the theory and analysis supporting its development. The section then details two major clutter-related developments, spotlight bistatic synthetic aperture radar (SAR), which can now generate high resolution images using bistatic autofocus and related techniques; and adaptive moving target indication (MTI), which allows cancellation of nonstationary clutter generated by moving (i.e. airborne) platforms through the use of bistatic space-time adaptive processing (STAP).

Supported by 202 equations and 170 illustrations, Airborne Early Warning System Concepts is an invaluable reference tool for a wide audience. It will be a welcome library addition for the engineer, scientist, system integrator, user, designer, or manager with interest in AEW concepts. It is also suitable for students and professors of electrical and system engineering or military science. This comprehensive discussion of airborne early warning (AEW) system concepts encompasses a wide range of issues, including capabilities and limitations, developmental trends and opportunities for improvement. Consisting of contributions from experts in the field, the book is presented at varying levels of complexity, ranging from elementary to advanced. For the generalist, the text provides a fundamental understanding of the status of AEW concepts with the use of only elementary mathematics. For the specialist, there are separate chapters that emphasize key AEW radar issues.

Radar interferometers provide a cost-effective radar architecture to achieve enhanced angle accuracy for enhanced target tracking. Presenting a comprehensive understanding of various radar interferometer architectures, Angle of Arrival Estimation Using Radar Interferometry aims to quantify interferometer angle estimation accuracy by developing a general understanding of various radar interferometer architectures and presenting a comprehensive understanding of the effects of radar-based measurement errors on angle-of-arrival estimation. The interferometer architectures described include a basic digital interferometer, a monopulse interferometer, an orthogonal interferometer and signal processing algorithms. By exploring interferometry and beyond, this book offers a unique perspective and an in depth look at the derivation of angle error equations for a radar interferometer as affected not only by additive noise but by other error effects such as multipath, glint, and spectral distortion. As such this book is primarily directed toward tracking radars but will also discuss imaging applications as well.

This book provides a unique overview of the broad field of space-time processing and is divided into two parts: the first dealing with the classical adaptive suppression of airbourne and spacebased radar clutter, and the second comprimising miscellanous applications in other fields such as communications, underwater sounds and seismics.

This is the only English language book on bistatic radar. It starts with James Casper's fine chapter in the first edition of Skolnik's Radar Handbook (1970), capturing previously unpublished work before 1970. It then summarizes and codifies subsequent bistatic radar research and development, especially as catalogued in the special December 1986 IEE journal. It defines and resolves many issues and controversies plaguing bistatic radar, including predicted performance, monostatic equivalence, bistatic radar cross section and resolution, bistatic Doppler, hitchhiking, SAR, ECM/ECCM, and, most importantly, the utility of bistatic radars. The text provides a history of bistatic systems that points out to potential designers, the applications that have worked and the dead-ends not worth pursuing. The text reviews the basic concepts and definitions, and explains the mathematical development of relationships, such as geometry, Ovals of Cassini, dynamic range, isorange and isodoppler contours, target doppler, and clutter doppler spread.

This book deals with the basic theory for design and analysis of Low Probability of Intercept (LPI) radar systems. The design of one such multi-frequency high resolution LPI radar, PANDORA, is covered. This work represents the first time that the topic of multi-frequency radars is discussed in such detail and it is based on research conducted by the author in The Netherlands. The book provides the design tools needed for development, design, and analysis of high resolution radar systems for commercial as well as military applications. Software written in MATLAB and C++ is provided to guide the reader in calculating radar parameters and in ambiguity function analysis. Some radar simulation software is also included.

Driver information and assistance systems have emerged as an integral part of modern road vehicles in order to support the driver while driving. They make use of the newest information technologies in order to enhance driver awareness, safety and comfort, and thereby avoiding driver errors and accidents. Driver Adaptation to Information and Assistance Systems brings together recent work by the Marie-Curie Initial Training Network ADAPTATION. The project has studied drivers' behavioural adaptation to these new technologies from an integrative perspective working under a joint conceptual theoretical framework of behavioural adaptation that can be used to generate research hypotheses about how drivers will adapt to information and assistance systems and to derive guidelines for the design and deployment of such systems. The book aims to provide the reader with a better understanding of drivers' adaptation processes over time in response to information and assistance system use at different levels (energetic, cognitive and motivational levels); an appreciation of the impact of specificities of drivers population on technology use and skill acquisition; insights on the effects of system functionality, design and reliability as important system characteristics influencing drivers' adaptation; and recommendations on research methods and appropriate tools to investigate adaptation processes.
